BUTTON.-

SPECIFICATION forming part of Letters Patent No. 324,303, dated August11, 1885.

Application filed January 23, 1885. (No model.)

To all whom, it may concern.-

Be it known that I, LON PAUL CONARD, a citizen of the Republic ofFrance, residing at London, England, have invented a new and usefulImprovement in Buttons, of which the following is a speciiication.

My invention consists in the combination, with a button-head and theshank,of aspringpressed shellwhich fits over or in the buttonhead, andis capable of rotary motion, leaves hinged to the shank, projectionsformed on said leaves, a cam adapted to engage the projections on theleaves, and a rod which connects the cam with the shell,and also in thecombination, with a button-headand the shank,of a springpressed shellwhich fits over or in the buttonhead and is capable of rotary motion, aprojection on the shell and a depression on the button-head, or viceversa, for locking the 2o shell, leaves hinged to the shank, projectionsformed on said leaves, a cam adapted to engage the projections on theleaves, and a rod which connects the camwith the shell.

In the accompanying drawings, Figure l rep- 2 5 resents a side elevationof myimproved button when in its normal position.- Fig. 2 is an endelevation of the same with part broken away. Fig. 3 is an end elevationwhen the springpressed shell is rotated. Fig.l 4 is a horizon- 3o talsection inthe planea` x, Fig. 2. Fig. 5 isa bottom view. Fig. 6 is avertical section in the plane y y, Fig. 7, of the spring-pressed shelland the shan-k detached. Fig. 7 isabottom view ofthe same.

Similarlettersindicate corresponding parts. v

In the drawings, the letter A designates the shank of the button,whichhas the hollow button-head B rigidly secured to one of its ends, andwhich shank may be made either hollow, slotted, or, as shown in thedrawings, may have A drilled into it a hole, a,which extends in thedirection of its length. C is a shell adapted to be fitted over thebutton-head B, and it is 5 subjected to the action of the spring b,coiled in the button-head. One end of the spring b is secured to a post,c, on the bottom of the button-head, or in any other suitable manner,

and the other end is fastened to a hook or post, o', on the shell C,Figs. 2 and 6.

To the other end of the shank A,before men- 5o tioned,are hinged twoleaves, D D', the hinges d d and d d of the two leaves being arrangedalternately-that is to say, so arranged that one hinge, d, and one, d',will be respectively the same distance from the center, or facing eachother.

On the innertwo hinges, d d'5, are formed projections e e,whichprojections are adapted to be engaged by a cani, E,which is connectedwith the shell C by a rod, f, and has two teeth 6o or projections, gg,which,when given a rotating mot-ion, engage the projections e e. oInstead of forming the projections e e on the respective hinges, thesame can be formed directly on lugs formed on the leaves D D'; but 65the method first described is considered the most expedient. The actionof the coiled spring b tends to keep the shell C in the position shownin Figs. 2,3, and 4, and when the shell occupies this position theleaves D D are 7o extended-that is to say, are in a plane parallel toplane of the button-head.

When thebutton is to beinsertedin the buttonhole of a cuff or the like,the shell C is rotated in the direction of the arrow, Fig. 4, wherebythe cam E is rotated in the same direction and engages the projections ggon the leaves D D', andthe same are brought into the posit-ion shown inFig. 3, and in order to hold them in this position, so as to facilitatethe con- 8c venience of its insertion, a small recess, 71., is formed onthe inner surface of the shell C, and a corresponding small projection,It', is madeA in the button-head B, both recess and projection being insuch a position that when the leaves are folded in the position showninFig.

4 the projection engages the recess. When it is desired to extend theleaves, a slight twist of the shell C willI disengage the projectionfrom the recess, and the force of the spring a 9o will return theshell() to its original position.

In the drawings, the cam E is shown as extending beyond the plane of theleaves when the same are extended; but in practice I place the cani soas to fall within or below the plane of the leaves, so that the sainecan in no inanner injure the person wearing the buttons.

Vllat I claim as new, and desire to secure by Letters Patent, is*

1. The combination, substantially as hereinbefore described, with thebnttolrhead B and the shank A, of asprililg-pressed shell,C, which fitsover or in the button-head, and is capable of rotary motion, the leavesl) D', hinged to the shank, the projections e e', formed on said leaves,the cam E, adapted to engage the projections on the leaves, and the rodf, which connects the cam with the shell.

2. The combination, substantially as hereinbefore described, with thebutton-head B and the shank A,ol` aspringjiressed shell, C, which litsover or in the button-head, and is capable of rotary motion, aprojection, 7L, in the shell, and a depression in the button-head for1oeking the shell, the leaves l.) 1)', hinged to the shank, theprojections e e', formed 011 said leaves, the cani E, adapted to engagethe projections on the leaves, and the rod which
